Hi
I am currently developping a model browser for a car crash application.
I am using GTK2.12 to populate all the objects that are in my car crash
model.
For this I used the standard GtkTreeModel / GtkTreeStore design pattern.
When the model is becoming really big (more than 250 000 objets

Currently this behavior is inconsistent in GTK+, as the GtkListStore and
GtkTreeStore still emit row-deleted *after* deleting a node. For the sake

I'm keeping some summary fields of a GtkListStore and I need to update them on
every model change. The problem is while catching the row-deleted signal
the row is yet deleted, so I can't access the row content to update my
summary fields.
How can I do it?
Thanks,

updations u want and then delete the row from the model.

It should be either through some key-press or mouse-click, in either case u
must select the row before selecting.

At first blush, after reading the Gtk+ 2.0 Tree View tutorial:

A GtkTreeModel/View seemed apropriate, but it would seem that the

Is $SUBJ possible [maybe in Gtk3]?
It could be really useful to not depend on whole gtk. After all, a
Gtk[Tree|List]Store is a data type like a GList...
At least if it was in glib it could be used in libgda, w/o having to
reinvent the wheel. Then some gnome-db widgets could become

Probably a hack but... if you append the row to a treepath greater than
that of the iterator, no problem. But if you append it to a path less
than that represented by the iterator, the iterator will be knocked off
track.

I have a code snippet that does just the same,

the second gtk_tree_model_get_iter_first() seems to succeed
but gives an invalid iterator, as I get invalid values.
